Rhexia aristosa

This perennial herb produces stiff stems up to about 70[2] to 100[3] centimeters tall. The leaves are linear to lance-shaped and up to 5 centimeters tall. The flowers have lavender petals up to 2 centimeters long. Flowering occurs in June through September.[2]

This species grows in several types of wetland, including bays, bogs, flatwoods, seasonally moist pools and meadows, and savannas. It is often a member of the flora in Carolina bays. It may grow in the understory of Taxodium ascendens with Panicum hemitomon, Polygala cymosa, Lobelia boykinii, Sagittaria spp., and Lachnanthes caroliniana. It is adapted to habitat that is prone to disturbance such as wildfire and flooding.[2]

This species is threatened by the loss of its habitat, for example, the loss of Carolina bays when they are converted to agriculture and silviculture and other uses. During development, the local hydrology is altered, eliminating natural springs and causing polluting runoff. The bays are also altered during logging operations.[2]
